        # The TLS Proxy allows for inspecting and manipulating TLS wrapped
        # protocols.
        #
        # ## Example
        #
        #     require 'ronin/support/network/tls/proxy'
        #     require 'hexdump'
        #
        #     Ronin::Support::Network::TLS::Proxy.start(port: 1337, server: ['www.wired.com', 443]) do |proxy|
        #       address = lambda { |socket|
        #         addrinfo = socket.peeraddr
        #
        #        "#{addrinfo[3]}:#{addrinfo[1]}"
        #       }
        #       hex = Hexdump::Hexdump.new
        #
        #       proxy.on_client_data do |client,server,data|
        #         puts "#{address[client]} -> #{proxy}"
        #         hex.dump(data)
        #       end
        #
        #       proxy.on_client_connect do |client|
        #         puts "#{address[client]} -> #{proxy} [connected]"
        #       end
        #
        #       proxy.on_client_disconnect do |client,server|
        #         puts "#{address[client]} <- #{proxy} [disconnected]"
        #       end
        #
        #       proxy.on_server_data do |client,server,data|
        #         puts "#{address[client]} <- #{proxy}"
        #         hex.dump(data)
        #       end
        #
        #       proxy.on_server_connect do |client,server|
        #         puts "#{address[client]} <- #{proxy} [connected]"
        #       end
        #
        #       proxy.on_server_disconnect do |client,server|
        #         puts "#{address[client]} <- #{proxy} [disconnected]"

        # ## Callbacks
        #
        # In addition to the events supported by the {Network::Proxy Proxy}
        # base class, the TLS Proxy also supports the following callbacks.
        #
        # ### client_connect
        #
        # When a client connects to the proxy:
        #
        #     on_client_connect do |client|
        #       puts "[connected] #{client.remote_address.ip_address}:#{client.remote_addre
        #     end
        #
        # ### client_disconnect
        #
        # When a client disconnects from the proxy:
        #
        #     on_client_disconnect do |client,server|
        #       puts "[disconnected] #{client.remote_address.ip_address}:#{client.remote_ad
        #     end
        #
        # ### server_connect
        #
        # When the server accepts a connection from the proxy:
        #
        #     on_server_connect do |client,server|
        #       puts "[connected] #{proxy}"
        #     end
        #
        # ### server_disconnect
        #
        # When the server closes a connection from the proxy.
        #
        #     on_server_disconnect do |client,server|
        #       puts "[disconnected] #{proxy}"
        #     end
        #
        # ### connect
        #
        # Alias for {#on_server_connect}.
        #
        # ### disconnect
        #
        # Alias for {#on_client_disconnect}.
